A walkie-talkie is a walkie-talkie, and its name comes from an old military radio station.
Development history:
1. Radio walkie-talkies are the earliest wireless mobile communication devices used by humans, and they began to be used as early as the 1930s. In 1936, the American company Motorola developed the first mobile radio communication product - the "Patrol Card" AM car radio receiver.
2. In 1940, the American Motorola Company developed the first handheld two-way AM radio walkie-talkie weighing 2.2 kg for the U.S. Army Signal Corps, with a communication range of 1.6 km.
3. In 1962, Motorola launched the first handheld wireless walkie-talkie HT200, which weighed only 935g. Its shape was called a "brick" and it was about the same size as an early mobile phone.
4. After nearly a century of development, the application of walkie-talkies has become very common, moving from specialized fields to general consumption, and from military use to civilian use. It is not only a professional wireless communication tool in mobile communications, but also a consumer tool with consumer product characteristics that can meet people's daily needs.
5. Nowadays, radio walkie-talkies are by no means an outdated product and will be used for a long time. With the development of economy and progress of society, people are more concerned about their own safety, work efficiency and quality of life, and the demand for radio walkie-talkies will also grow day by day. The extensive use of walkie-talkies by the public has further promoted radio walkie-talkies to become a communication tool that people love and rely on.
